Most specimens were photographed upon collection; tissue samples were taken and deposited at the tissue collection of the CPUM. Fishes were identified using the keys and descriptions from Springer , Allen and Robertson , , , Fisher et al. The systematic arrangement followed Nelson et al. The current taxonomic status of each species was corroborated in Eschmeyer et al. The arrangement of the genera and species was in alphabetical order.

In the systematic list, the habitat-type from which each species was collected and the scientific collection by which the specimen was identified, or the scientific document from which information of the specimen was obtained, are indicated. Finally, a zoogeographical affinity analysis of the species, based on the biogeographical regionalization proposed by Briggs , , was made. Accordingly, the Tropical Eastern Pacific was divided into three provinces.

The San Diegan province was also included, since some species tended to have a northern distribution. Sampling was performed in 13 intertidal pool sites, 20 rocky reef sites, three coralline communities, two artificial reefs, 22 estuarine ecosystems, and 50 soft bottom and open sea sites, collecting fishes. The families representing the greatest number of species were Sciaenidae 30 , Carangidae 26 , Haemulidae 24 , Serranidae 21 , and Paralichthyidae and Gobiidae Record from literature: Castro-Aguirre et al.

Fishery importance: personal consumption A , commercial use C and discarded I. The artisanal fishery captures yielded species. The families with the highest number of species were Carangidae 17 , Haemulidae 15 , Sciaenidae 13 , Serranidae 10 , and Lutjanidae 7. The largest number of species, The introduced species Pterygoplichthys disjuntivus Weber, and Cyprinus carpio Linnaeus, were also omitted. This could be related to the sampling methods employed, which had not been previously used; the few previously reported species with cryptic behavior were primarily bycatch Madrid-Vera , Castro-Aguirre et al.

In general, the number of species in the area may be increased if sampling effort is expanded and records from shrimp and tuna bycatches are included. In artisanal fishing Fig. Alectis ciliaris , Bloch, , Lutjanidae e. Lutjanus guttatus , Steindachner, , Paralichthyidae e. Centropomus armatus , Gill, , and Serranidae e. Most of the elasmobranch capture, with the exception of the fins, is considered of low economic value.

A high number of neonatal and juvenile hammerhead sharks Sphyrna sp.

In general, the elasmobranchs, due to their unique biological and ecological characteristics, present low population growth and are considered highly vulnerable Frisk et al. We accordingly recommend review and enforcement of the relevant legislation. Species with no current market value may have high nutrient value; hence the number of species with potential to be commercialized is underestimated. In offshore fisheries, these species often have commercial value. Trichiurus nitens Garman, supports a small fishery in the central portion of the littoral zone of Ecuador pers.

We have confirmed the distribution of such fish, as exemplified by the first formal record of 24 ecologically cryptic species. Our work expanded on the most complete fish fauna checklist previously available for the area by Hastings SIO , for their assistance in the identification of the collected organisms and for information provided.

DUC receives $2 million to restore important coastal habitats

Freshwater mixing with the salty Pacific creates the Fraser River Estuary—a highly productive and diverse network of marshes, mudflats and tidal waters home to hundreds of species of plants and animals. Approximately 57 acres 23 hectares will be restored to improve the function of the Fraser River Estuary. Staff will be breaching dikes, modifying water controls and delivering other conservation work to enhance the important exchange of tidal water throughout the estuary.

Benefits will be far-reaching. Every year millions of juvenile fish travel to the estuary en route to the ocean, making it a critical feeding and rearing area. Other species including Pacific herring, sturgeon, eulachon and smelt, as well as Dungeness crab and shrimp also rely on the brackish estuary waters to gain strength, size and stamina. The fishing industry is one of the largest and most successful in B. Ensuring nurseries like the Fraser River Estuary remain healthy is key to ensuring healthy fish populations now and into the future.

Her experience and interests include: environmental policy, planning, plastic consumption, responsible fisheries, good environmental practices, invasive land and marine species. She is interested in small scale fisheries reform in developing countries. More specifically, through a multidisciplinary approach ensuring conservation impact and with opportunities for scaling.

He goal is to better understand and contribute to the dynamic and innovative solutions including fisheries science and ecology, communities, livelihoods, market based initiatives and policy. She has worked on various sustainable fisheries management projects including design of marine protected areas, economic alternatives, seaweed aquaculture, traceability and adaptive management framework.

She has experience collaborating with a diverse group of stakeholders, government agencies, NGOs, local communities and the private sector. As a SCUBA Divemaster she fell in love with the marine environment, which fuels her professional aspirations to influence ocean conservation and her specialization in Coastal Marine Resource Management at the Bren School. Upon graduating, Vienna plans to focus on marine reserve creation, implementation and management, specifically in ocean areas beyond national jurisdiction.
